Maggert won the U.S. Senior Open on Sunday for his second major victory on the Champions Tour this year. He closed with a 5-under 65 at sun-drenched Del Paso Country Club, edging defending champion Colin Montgomerie by two strokes.

Maggert had just three wins in more than 20 years on the PGA Tour. Now he has matched that total in a little more than a year on the Champions Tour.

"I had a lot of good runs in the U.S. Open over the years and probably lacked a little maturity to pull it off," he said. "But certainly, now that I'm an old guy, I've learned a lot and was able to just steady myself and play well."

Maggert made six birdies and one bogey to finish at 10-under 270. He took home $675,000, a gold medal, a trophy and an exemption into next year's U.S. Open at Oakmont.

Montgomerie, 52, closed with a 66. Grant Waite and Langer tied for third at 7 under. Waite had a 67, and Langer shot a 68.

But nobody could overtake Maggert, who provided a little bit of drama to a final round that lacked it when his approach on the 18th landed in the upslope of the greenside bunker. He wedged out and made the four-foot par putt, raising his arms in celebration.

Maggert embraced his wife, Michelle, and their 10-year-old children, twins Madeline and Jake, who came running onto the green - with Madeline leaping into his arms.

His family had taken a flight from South Carolina and showed up on the practice range before Maggert began his round. They had missed his other victories on the Champions Tour and didn't want to miss another.

"It was a little bit of an extra, 'hey, they came all the way here. Don't screw this up,' " Maggert said, chuckling.

After three days that ended with bunched leader boards, Maggert made three birdies to start his round to quickly pull away. He hit 12 of 13 fairways and consistently reached greens in regulation.

Maggert also drove the green on the 282-yard, par-4 ninth, then converted a birdie putt to move to 9 under. He stuck his tee shot within five feet on the par-3 14th before converting another birdie. He just about sealed his victory by reaching the par-5, 550-yard 15th in two, then two-putting for a three-shot lead.

Maggert bogeyed the 16th but stayed out of trouble from there to make sure nobody could catch him from the clubhouse.

Tom Watson missed his chance to carve his place as the oldest winner of a senior major at age 65. He started one off the lead but was never a factor, shooting a 69 to tie for seventh at 5 under.
